The press conference was held on Friday afternoon. Traditionally that is the time when press conference are held about stories that are seeking NO or MINIMAL coverage because the stories run in the Saturday papers which are not read as much because people do other things on the weekend.
With the 24/7 news cycle, the internet, instantaneous access to info Friday news might be more available but I got to wonder why they didn't release the story for the SUNDAY paper. Here's a link to the Chicago Sun Times article. I'm concerned about the "rolling" street closure when the "leaders" are carted around the city for events.
I wonder what the NATO roadblocks will look like. I don't think they will just put up sawhorses and be done with it. I think they will be "manned" to some degree.
